Getting Verification Right

The purpose of the book is to train verification engineers on the breadth of technologies available and to give them a utilitarian methodology for making effective use of those technologies. The book is easy to understand and a joy to read. Its organization follows a ‘typical’ verification project from inception to completion, (planning to closure). The book elucidates concepts using non-technical terms and clear entertaining explanations. Analogies to other fields are employed to keep the book light-hearted and interesting.

This book constitutes the refereed proceedings of the international symposium Formal Methods Europe, FME 2002, held in Copenhagen, Denmark, in July 2002. The 31 revised full papers presented together with three invited contributions were carefully reviewed and selected from 95 submissions. All current aspects of formal methods are addressed, from foundational and methodological issues to advanced application in various fields.

CHARME’99 is the tenth in a series of working conferences devoted to the dev- opment and use of leading-edge formal techniques and tools for the design and veri?cation of hardware and systems. Previous conferences have been held in Darmstadt (1984), Edinburgh (1985), Grenoble (1986), Glasgow (1988), Leuven (1989), Torino (1991), Arles (1993), Frankfurt (1995) and Montreal (1997). This workshop and conference series has been organized in cooperation with IFIP WG 10. 5. It is now the biannual counterpart of FMCAD, which takes place every even-numbered year in the USA. The 1999 event took place in Bad Her- nalb, a resort village located in the Black Forest close to the city of Karlsruhe. The validation of functional and timing behavior is a major bottleneck in current VLSI design systems. A predominantly academic area of study until a few years ago, formal design and veri?cation techniques are now migrating into industrial use. The aim of CHARME’99 is to bring together researchers and users from academia and industry working in this active area of research. Two invited talks illustrate major current trends: the presentation by G ́erard Berry (Ecole des Mines de Paris, Sophia-Antipolis, France) is concerned with the use of synchronous languages in circuit design, and the talk given by Peter Jansen (BMW, Munich, Germany) demonstrates an application of formal methods in an industrial environment. The program also includes 20 regular presentations and 12 short presentations/poster exhibitions that have been selected from the 48 submitted papers.

Wolfgang Ruck 1 Institute of Natural and Technogenic Disasters, Udmurt State University, Izhevsk (Russia), 2 Institute of Ecology and Environmental Chemistry, University Lüneburg (Germany) During the Cold War a whole arsenal of deadly chemical weapons was allowed to build up on both sides of the ideological divide. Happily, today the problems are reversed. Expertise is now required in the field of safe and environment-friendly disposal of chemical weapons and cleaning up of contaminated sites all around the world, but not least in the ex-Soviet-led countries. The participants and speakers to the NATO-Russia advanced research workshop on the “Ecological Risks Associated with the Destruction of nd th Chemical Weapons”, hosted by the University of Lüneburg on 22 - 26 October, 2003, therefore, came from many different parts of the world. Of the eight countries represented at the workshop, two were ex-Eastern- Block, and six were Western countries. Yet the West was by no means overrepresented. On the contrary, the Russian expert-speaker contingent, with 33 participants, did justice to the size of their country – and to their chemical-weapons problem – and provided the majority of active participants. In all, there were 57 participants, of which 11 dispatched from the TACIS project “The development of the chemical weapons” facility at the detached plant No 4 of OAO Khimprom, Novocheboksarsk.

This book focuses on web service specification, search, composition, validation, resiliency, security and engineering, and discusses various service specification standards like WSDL, SAWSDL, WSMO and OWLS. The theory and associated algorithms for service specification verification are detailed using formal models like Petrinet, FSM and UML. The book also explores various approaches proposed for web service search and composition, highlighting input/output, parameter-based search, and selection of services based on both functional and non-functional parameters. In turn, it examines various types of composite web services and presents an overview of popular fault handling strategies for each of these types. Lastly, it discusses the standards used for implementing web service security on the basis of a case study, and introduces the Web Service Development Life Cycle (WSDLC), which defines co-operation between several industry partners to develop web services in a more structured way.

"Wise old Vergil says in one of his Georgics, 'Praise large farms, stick to small ones,'" Robert Frost said. "Twenty acres are just about enough." Frost started out as a school teacher living the rural life of a would-be farmer, and later turned to farming full time when he bought a place of his own. After a sojourn in England where his first two books were published to critical acclaim, he returned to New England, acquired a new farm and became a rustic for much of the rest of his life. Frost claimed that all of his poetry was farm poetry. His deep admiration for Virgil's Georgics, or poems of rural life, inspired the creation of his own New England "georgics," his answer to the haughty 20th-century modernism that seemed certain to define the future of Western poetry. Like the "West-Running Brook" in his poem of the same name, Frost's poetry can be seen as an embodiment of contrariness.
